This invention relates to vaporizing means and more especially to means for effecting the dispensation of Waste fluids in a refrigeration system, although certain features thereof may be employed with equal advantage for other purposes.

It contemplates more especially the provision of means in association with a refrigeration system to effect the dispensation and evaporation of Waste liquids resulting from surface condensation.

Surfaces exposed to differences of temperature in the presence of a moist atmosphere are apt to be coated with a film of condensate which should be removed substantially coincident with the formation thereof in order to prevent oxidation and frostation when subjected to freezing temperatures. This is especially important in refrigerating systems wherein the instrumentalities are usually coated with a condensate which forms an insulation responsive to the frostation thereof, thereby impeding the thermal transmission through'the walls of the instrumentalities vwhich are provided for that purpose.

`One object of the` present invention is to provide means for effecting the drainage of 'thef condensate film from the surface of instrumentalities prior to the 'frostation thereof.

Another object is the Provision of means for effecting the vaporization of waste liquids to enable the convenient dispensation thereof.

Still another. object is the provision of means in association with a condensing unit to effect the removal of the Waste liquids drained from instrumentalities employed in connection with the refrigeration system.

A further object is to provide means in association with an air draft to effect \vaporization of liquids.

A still further object is the provision of a serrated surface for receiving a liquid thereover to effect the vaporization thereof by directing air thereagainst.

Still a further object is to provide means in association with a fan of a condensing unit to effect the vaporization of waste liquids Serial N o. 196,722.

collected from the instrumentalities of a re- Y frigeration system. l

Other objects and advantages Will appear from the following description of an illustrative embodiment of the present invention.

In the drawing:

Figure 1 is a view in elevation of a device embodying features of the present invention.

Figure 2 is a sectional view taken substantially along line II-II of Figure 1.

Figure 3 is an end sectional view in elevation of the structure disclosed in Figure 1.

Figure 4 is a fragmentary view of the device employed in connection with an instrumentality to collect the condensate therefrom.

The structure selected for illustration comprises a refrigerator cabinet 10 of-any desired configuration which is shaped to define a food compartment 11 and a condenser unit compartment 12 disposed therebelow.

The condenser compartment 12 contains a condenser base 13 which supports a compressor 14 thereon in association with the condenser coils 15 disposed on either side thereof. 75 A motor 16 is fixed to the base 13 in any appropriate manner so that the armature shaft 17 thereof may carry a pulley 18 in alignment with a flywheel 19 fixed to the crankshaft 20 lof the compressor 14.

The flywheel 19 is geared to the pulley 18 by virtue of a iexible chain 21. The refrigerant is withdrawn in vapor form from the evaporator 25 through a conduit 29, after which it is compressed in the compressor 14,

condensed in the condenser, and collected in a receiver 22 from whence it is fed to the expanison valve 24. The expansion valve 24 of the pressure control type, it being fixed to an evaporator 25 toefl'ect' the expansion of the refrigerant and consequent vaporization thereof to impart the desired cooling ofthe surrounding medium.' The vaporized refrigerant is discharged from the evaporator 25 through a union 26 in communication with a tube 27 which directs the return of the refrigerant to the low side of the compressor 14 to complete a continuous cycle.

As shown, the lower surface of the evaporator 25 is provided witha series of inclined voi surfaces 30 which are disposed at the critical drainage angle to eiectthe iiow of the condensate thereover. The surfaces 30 terminate in oppositely inclined surfaces 31 to form a series of spaced ridges 32 Wherefrom the condensate drips. Arcuate troughs 33 terminating in end plates 34 are secured in any suitable manner as at 35 to the evaporator casing in association with the ridges 32 so as to support the troughs' in a position to collect the condensate therefrom. The troughs 33 are slightly inclined so as to effect the discharge of the rcondensate through an orifice 36 provided in the end face 34 Vof the trough 33 to discharge the condensate to a transversely disposed inclined trough 37 which terminates in a waste discharge tube 38 at one extremity thereof.

To enable the control of the thermal transmission and radiation between the evaporator 25 and the food compartment 11, the

troughs 33 are provided with laterally projecting plates or lins 39 which tend to impede transmission of heat therebetween, it serving to obstruct the usual path of transmay be extended at any' desired angle to elfect the proper impedence necessary to maintain the compartment 11.

The' discharge tube 38 extends downwardly in a vertical direction, it terminating in disposed directed against the screen 41 to effect the a condensing unit chamber 12 which is provided With a horizontally disposed trough 39 for receiving the liquid from the tube 38. The trough 39 is provided with a series of apertures 40 along the arcuate edge thereof to direct the flow of the condensate over any suitable surface such as the screen 41 which is tensionedwithin a frame 42 fixed to the base 13 by means of a bracket 43.

-With the arrangement of parts above described, the condensate will trickle-over the screen 41 in the path of an air draft occasioned by the rotation of the iiywheel 19 which is rovided with a series of Aangularly blades 44 for that pu ose. Flywheel 19 produces an air dra which is vaporization of the liquid trickling thereover, thus creating the desired cooling effect within the chamber 12. It will be apparent that novel means have been provide to effect the vaporization of uids without necessitating the provision of the waste basin which usually requires much care and a comparatively lar e installation cost.

arious changesmay be made in the embodiment of the invention herein speciically described without departing from or sacrificing any o f the advantages thereof describedin the'appending' claims.

I claim:

1. The combination with a surface .having a condensate film thereon, of means for collecting said condensate, means for effecting the vaporization of said condensate, said vaporizing means comprising a perforated screen over which said condensate trickles, and a fan in juxtaposition to said screen to direct a draft of air against said screen.

2. In a refrigeration system, the combination with a condensing unit, of a fan for driving an air current thereacross to absorb the heat' of condensation, an evaporator in communication with said unit, means for draining the condensate from the exterior of said evaporator, a meshed wire grid for receiving said condensate, and to permit ofsaid condensate trickling thereover, said fan in association with said condensing unit being directed toward said id to eifect the vaporization of the con ensate trickling over said grid.
